CAR-AXLE LUBRICATO R.

SPECIFICATION forming part of Letters Patent No. 461,265, dated October 1 3, 1891.

Application iile'd December 1, 1890. Renewed July 24,1891. Serial No. 400,583- (No model.)

To all whom it may concern,.-

Be ity known that I, FRANK J. LEIBMANN, a citizen of the United States, residing in the city, county, and State ot' New York, have invented certain new and useful Improvements in VCar-Axle.Lubricators, of which the following is a specification.

This invention relates to certain improvements in the caraxle lubricator for which Letters Patent No. 315,042 were granted to me under date ot April 7, 1885, the improvements being designed with a view to simplify the application of the lubricator and permit the same to be easily inserted into and removed froni the car-axle box and to make the construction stronger and more durable; and the invention consists of a lubricating bricator assumes its normal position, so as to apply the lubricating-oil to -thej'ournaL The lubricator is composed of arectangular main frame, which is supported on pivoted and spring-cushioned legs having eccentrics at their upper ends that are acted upon by tlat springs inserted into the trame. A contactroller is supported below the axle in bearings guided in longitudinally-slotted boxes and rotated by contact with the journal. A second roller is arranged in guide-boxes below the upper roller and provided with a wiper that takes up the oil and transmits it to the intermediate contact-roller and from the same to the journal. The guide-boxes containing the bearings of these rollers are pivoted to the main trame and adapted to be swung approximately up into the plane of the same, in which position they are held by means of springs that pass on the flat side portions of the guide-boxes, while when the lubricator is in use the guide-boxes and rollers are supported at right angles to the main frame by the springs pressing on the upper ends of the guideboxes.

In the accompanying drawings, Figure 1 represents a vertical longitudinal section of a carlaxle box, showing my improved lubricating attachment in position in side elevation as applied to the oar-axle. Fig. 2 'is a side elevation of the lubricating attach ment, partly in section, and drawnon a larger scale. Fig. 3 is aplan of the same, also partlyin section. Fig. 4 is a front elevation of the lubricating attachment; andv Figs. 5 and 6 are a side and top View of the same, arranged in liattened position ready to be introduced into or removed from the car-axle box.

Similar letters of reference indicate corre sponding parts.

A in the drawings represents a car-axle, B a car-axle box, and C the lid of the same.

Below the journal ot the car-aXleA is located a spring-cushioned lubricator D, which consists of a metallic rectangular main frame a, which is supported on legs l) b that are pivoted to recesses of the main frame a and connected in pairs by means of transverse rods b near their lower ends. rlhe pivots of the supportingslegs b are provided at their inner ends with eccentrics b2, which are acted upon by flat transverse steel springs b3, the ends of which are inserted into recesses of the main frame a, as shown clearly in Fig. 2. The flat springs b3 serve to exerta spring-acvtion'on the supporting-legs b b and to press thereby the main frame a, which is provided at the front and rear sides with segmental recesses for theA axle-journal in upward direc'- tion toward the journal, while the lower ends of the legs rest on the bottom of the car-axle box. 'lo the central recesses a of the front and rear sides of the main frame a lare pivoted longitudinally-slotted 'guide-boxes E, which are closed at their upper and lower ends and provided With longitudinal grooves, in which the bearings e e and the spindles ff of an upper contact-roller F and a lower frictionroller F', which is in contact with the upper roller F, are supported. The bearings e of the lower roller F are supported on spiral springs f2, which are located in the lower parts of the grooves of the guide-boxes and which serve to press the lower roller against the upper contact-rollerF and to hold thelatter in contact with the axle-journal. To the lower roller F is applied a wiper gv of leather or other suitable material, which is ap plied to the middle contracted portion of the lower roller F', said Wiper dipping into the oil and bringing the same in Contact with the roller F and ICO by the latter with the journal at every rotation of the carSaXle. The cushioning-springs of ythe lower roller F impart the required elasticity to the bearings of the upper contact-roller F, so that the same is held in contact With the axle-journal.

Flat springs h are attached to the main frame a, below the segmentally-recessed ends of the same, which springs bear on the upper ends of the slotted guide-box E and hold the saine and the rollers F F below the axle in a position `at right angles to the main frame ot, as shown in Figs. 3 and 4. When it is desired, however, to remove the lubricator from the car-axle boX, the rollers F F are swung with their pivoted guide-boxesA approximately into the plane of the main frame a at the interior of the same, as shown in Figs. 5 and 6, in which position the transverse springs h bear on the straight upper ends of the guide-boxes E and retain the same in p0- sition by preventing them from dropping again into vertical position at the center of the main frame a. When the contact-rollers F F are in this position, the yoke-shaped legs can be readily moved against the tension of. their springs b3 into line with the sides of the main frame a, as shown in Fig. 5, so that the height of the lubricator is greatly reduced, in which position it can be readily removed from below the axle-journal and taken out of the axle-box, in case it should 'be necessary to put in a new wiper or exchange other parts, and' replaced in position below the car-axle.

When the lubricator is inserted below the axle-journal, the contact-rollers are turned in downward direction by pressure of the liingers until the resistance of the springs his overcome. When they arrive in a vertical position below the car-axle, the springs h bear on the upper ends of the guide-boxes E and hold them in vertical position, so that the con-` tact-roller F and wiper-roller F can perform the work allotted to them.

As compared'with my former lubricator, it will be seen that the main difference consists in the arrangement by which the entire device can be elongated or flattened out, whereby the insertion and removal of the lubricator into or from the car-axle box is facilitated and in a stronger and simpler construction of the durable and effective in use.

Having' thus described my invention, I

claim as new and desire to secure by Letters Patentl. A lubricator for car-axles, consisting of a spring-supported main frame, guide-boxes pivoted to said main frame, a contact-roller supported in bearings of said guide-boxes, a second roller below the contact-roller supported in spring-cushioned bearings of the guide-boxes, a wiper attached to the lower rollers, and means for retaining the guideboxes and rollers in a position at right angles to the main frame orin a plane with the same, substantially as set forth.

2. The combination of a main frame, supporting-legs pivoted to the same and provided with eccentrics at their upper ends, transverse cushioning-springs bearing guide-boxes pivoted to the main frame on said eccentrics, a contactroller supported in bearings guided in said boxes, a transmitting-roller supported below the contact-roller in spring-cushioned bearings in said guide-boxes, a wiper applied to the middle contracted part of the lower roller for transmitting the lubricating-oil to the contact roller and axle, and lockingsprings for the guide-boxes, substantially as set forth.

3. The combination of a main frame supported on spring-cushioned legs pivoted to the main frame, longitudinally grooved and v slotted guide-boxes pivoted centrally to the main frame, a contact-roller supported in bearings guided in said boxes, a lower wipercarrying roller supported on spring-cushioned bearings of the guide-boxes below the contact-roller and held in frictional contact therewith, retaining-springs attached to the main frame and adapted to hold the guide-boxes, and oil-transmitting rollers at right angles to the main frame or approximately in one plane therewith, substantially as set forth.

[n testimony that I claim the foregoing as my inventionI have signed my name in presence of two subscribing witnesses.
